JOHN OARRINGTON BROOKE, OF CINCINNATI, OHIO.

SCHOOL DESK AND SEAT.

Specification of Letters Patent.

' Patented June 2,1908.

Application fiIed May 29, 1907. Serial No. 376,405.

To all whom it may concern:

Be it known that I, JOHN OARRINGTON BROOKE, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Combined School Desks and Seats, of which the following is a specification.

The first part of my invention relates to an improved two part side frame or standard for supporting a desk body in which my I object is to provide a light, strong and durable support which may be made of reinforced malleable cast steel and can be readily ad'usted to accommodate pupils of different he1ght of body. 4

The second part of my invention relates to an improved desk body in which my object is to provide means whereby the same can be adjusted horizontally toward or from the adjacent seats to accommodate pupils having different sized bodies.

The third part of my invention relates to.

an improved seat support in which my object is to provide means for adjusting the seat bracket supporting arm horizontally so as to seat the pupil at the proper distance from the desk and thus be placed in correct position to avoid discomfort during school hours.

With these and other objects in view, so as to perfect such a structure, my improvements consist in the novel features of construction hereinafter described and claimed. 1

In order that my invention may be fully understood I will proceed to describe it with reference to the accompanying drawings in which:

Figure 1 is a side elevation of my improved combined school desk and seat showing the seat raised. Fig. 2 is a front view of one end thereof. Fig. 3 is a back view of the same. Fig. 4 is a vertical transverse section showing the seat lowered.

In carrying out my invention I providea pair of two part extensible side frames, or standards, the upper parts of which form vertically adjustable supports for the desk body and seat. These side frames are constructed of malleable cast steel so as to combine lightness and strength with durability and each side frame is formed with outer lower parts and inner upper parts adjustable upon the lower parts. 21 is the fixed lower part of a side frame providing a rigid base and is formed in one piece with a vertical thin web 22 of approximately triangular shape, a central vertical bolt slot 23, an exterior elliptical marginal flange 24 surrounding the vertical bolt slot 23, curved marginal flanges 25 capping the side edges of the web 22, an exterior horizontal marginal flange 26 at the top -of the web 22, approximately triangular openings 27 between the vertical bolt slot 23 and the side edges of theweb 22 in the lower part of the latter, exterior triangular marginal flanges 23 extending around the triangular openings 27 parallel vertical guide flanges 29 spaced'apart at the inner side of web 22, providing a vertical slide recess 30, and between which the vertical bolt slot'23 is located, and pairs of endfeet 31 having holes 32 for suitable fastenings 33 and intermediate pairs of bracing feet 34, beneath the slide recess30, and having holes 35 for suitable fastenings 36 whereby the side frames are secured rigidly toa floor.

37 is an inner plain vertically arranged rectangular plate forming the movable upper part of a side frame, adapted to slide in the vertical recess 30 between the parallel vertical guide flanges 29, and having superposed bolt holes 38 in its lower end, su erposed bolt holes 39 in its upper end, and superposed screw holes 40 intermediate of its ends at its front edge. j a

41 are lower bolts extending through the vertical bolt slots 23 of the lower part 21 and through the superposed lower bolt holes 38 of the upper parts 37 having their heads 42 bearing against the marginal flanges 24 and provided with binding nuts 43 whereby the upper parts 37 are adjustably held upon the lower parts 21 at the desired height.

44 is a wooden brace rail and 45 are wood screws inserted through the superposed intermediate screw holes 40 and into the ends of the brace rail 44 by which the upper parts 37 of the side frames are secured together at their outer edges, and indirectly brace the side frames.

are a pair of side pieces formed with superposed horizontal bolt slots 51 in their lower parts, each surrounded by reinforcing correspondingly slotted outer plates 52 secured by suitable fastenings 53. Extending through these outer plates 52, bolt slots 51, and the superposed upper bolt holes 39 of the upper parts 37 of the side frames are bolts 54 having their heads 55 bearing agamstthe outer plates 52 and horizontal adjustment.

57, is a suitable curved seat-back secured to the rear edges of the side pieces 50, and extending thereabove, by means of bolts 58 and nuts 59 to the outer wings of angle lates 60 whose inner wings are secured by suitable fastenings 61 to the side pieces 50.

120 are bracket arms constructed of malleable cast iron and each formed in one piece with a flat body 121, an offset inner upper part 122, having reinforcing end flanges 123, and secured by rivets 124 to the outer edges of the upper parts 37 of the side frames. The outer faces of the bracket arms 120 are reinforced by an inner marginal flange 125 and an outer marginal flange 126. The lower part of the body 121 of each bracket arm is also formed with a pair of horizontal reinforcing and guide flanges 127 spaced apart to provide a slide recess 128 in the web between the flanges 127.

129 is a bolt hole.

130 is the inner arm and 131 the outer arm of a'pair of two arm seat-brackets for a seat 132, having a hinge joint 133, similar to that described, shown and claimed in Patent Number 7 07,547, issued to Finley S. Brooke, August 26, 1902. In the present instance the inner arm 130 is formed of malleable cast steel with a lower art 134, longitudinally adjustable in the sli e recess 128 between the guide flanges 127 and having a longitudinal olt slot 135 and an offset rounded upper part 136 which carries the hinge-joint 133. This inner arm 130 has a reinforcing marginal flange 137. 138 is a clamping bolt extending through the bolt hole 129 in the lower part 121 of the bracket-arm 120 and through the bolt slot 135 in the lower part 134 of the inner arm 130, and having a head 139 bearing against the lower part 121 and securing nut 140.

By constructing the supports of the desk of malleable cast iron the possibility of breakage is avoided.

As the side frames, desk body and seat brackets are all adjustable only two sizes of desks are required to accommodate pupils from the kindergarten to the high school and in each instance these parts can'be adjusted by using a common wrench. The center fastenings for the side frames in addition to the end fastenings,render these light parts quite rigid and immovable so that independent seats need not be used.

Having thus described my invention the following is what I claim as new therein and desire to secure by Letters Patent:
